SPECIFICATION forming part of Letters Patent No. 366,958, dated July 19,1887.

(No model.)

To all whom it may concern:

Be itknown that I, J ULIUs HERMAN HOLM- GREEN, a citizen of the UnitedStates, residing at San Antonio, in the county of Bexar and State ofTexas, have invented a new and useful Improvement in Motors, of whichthe following is so full, clear, and exact a description as will enableothers skilled in the art to which my invention appertains to make anduse the same, reference being had to the accompanying drawings, in whichFigure 1 is a perspective of my improved device, showing the sameattached to a sweep for running a drill, a vertical reciprocating saw,or a pump, or any device in which a re ciprocating motion is desired.Fig. 2 is a side elevation of my improved device. Fig. 3 is a front viewof the same. Fig. 4c is a detail View of apart of an adjusting deviceused for adjusting the length of the stroke of the motor. Fig. 5 is asimilar detail view of the serrated plate which meshes with the plateshown in Fig. 4 for forming the adjustment referred to.

The object of my invention is to construct a device which may be usedfor pumping, sawing, drilling, and other analogous purposes, which willbe effective in its operation, and which will not be liable to get outof order, and the parts of'which will not be liable to get out ofalignment with each other. To this end it consists in making the devicetriangular and mounting the fly-wheel on the shaft, which holds theupper end of the frame firmly to: gether.

Heretofore great difficulty has been experienced with devices of this characterand great disadvantage has resulted from the wrenching andtwisting of the parts and the frame, which resulted in lost motion andirregular movement, and my object is to obviate these disadvantages; andto that end it consists in construeting a frame triangular in shape,rigidly secured together, as will be hereinafter dcscribed,and thegear-wheels and the shafts upon which the same are mounted are to bemounted one directly above the other in the manner shown.

In the accompanying drawings, A A designate the main stays or sidepieces, which are triangular in shape and which are bolted together attheir lower extremities by the bolts or rods c a, and which are rigidlysecured together at the top by the rod or shaft to. These stays are alsoprovided with cross-braces A A.

which are in this instance formed integral with' the main stays. Thesecross-pieces are provided centrally with suitable journal-boxes, inwhich is mounted the shaft B. This shaft B is provided at one end withan ordinary knuckle-joint, O, and at its opposite end with a crank-arm,D, having a wrist-pin, D, to which is secured the lever E.

The rod a, which secures the upper portion of the frame rigidly inplace, has looselyjournaled thereon a ily-whcel, B, the hub of which isprovided with a pinion, B, which is rigidly secured to the fly-wheel Bat its hub and may be formed integral therewith.

The fly-wheel may be flat to receive a belt.

The fly-wheel and the pinion B rotate to gethcr and are journaled on therod or shaft a. Directly beneath the pinion 13 is a cogwheel, 0, whichis rigidly keyed to the shalt B, journaled in the journal-boxes a" a,and this cog-wheel O imparts motion to the flywheel B through the mediumof the pinion B. Motion is imparted to the device through theknuckle-joint O, which is connected in any suitable manner with arotating rod, which may be run by horse-power, water-power, or

any other suitable motive power which it may be found desirable to use.

The crank-lever D is adjustable by' means of the corrugations D (shownin detail in Fig. 5,) and the two plates 1) D may be bolted together atany desired adjustment through the perforations d d and by a suitablebolt, (1, (shown in Fig. 3.)

From the foregoing it will be observed that the device is constructedtriangular in shape and is securely and firmly held in place by rigidrods at its three extremes, which makes a very strong and compactdevice. In this instance the whole device is constructed of metal, thefly-wheel and pinion B being rig idly secured together and journaledloosely on the rod or shaft to in the top of the frame, making a devicein which. the friction is comparatively slight.

It will also be observed that the main rods or shafts supporting therunning-gear are mounted in the frame one directly above the other, thuspreserving the center of gravity 1. In a motor of the characterdescribed,

the combination of the main stays made triangular in shape and rigidlysecured together at their three extremes, the rod at the top of themotor which serves as a stay for the frame and forms a bearing for thefly-wheel, which is journaled loosely on said rod, a pinion formedrigidly with the fly-wheel, and a second rotating shaft journaledloosely within the frame directly beneath the fly-wheel and pinion, saidrotating shaft having a gearwheel which imparts motion to the pinion andfly-wheel, all constructed to operate substantiall y as and for thepurposes specified.

2. The main frame made triangular in outline and provided with twocross-beams midway between the extremities of the side pieces, and arotating shaft journaled between the side pieces and within suitablejournal-boxes, said rotating shaft having a joint at one end and anadjustable crank-arm at the other, and a cog-wheel rigidly secured tothe shaft, with a fly-wheel and its pinion journaled loosely on therigid shaft in the top of the frame, all constructed to operatesubstantially as and for the purposes specified.

In testimony that I claim the above as my invention Ihereunto set myhand in the presenee of two subscribing witnesses.
